Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a chain for multi-level parking lots that can operate smoothly and improve safety by preventing derailment of the chain.

[Conventional technology]

A multi-story parking lot is known in which a plurality of cage bodies b for accommodating vehicles such as automobiles, motorized motorcycles, and bicycles are hung between two rotating chains to store the vehicles three-dimensionally.

Conventionally, in the case of such multi-story parking lots,
As shown in the figure, support metal fittings c for attaching cage body b are arranged on chain a every few links, and support metal fittings c
A guide rail d arranged in the direction of movement of chain a
Further, each roller e... was provided with a flange f oriented inwardly to prevent the chains a, a from wobbling laterally.

[Problem that the invention attempts to solve]

However, in this type of vehicle, if the vehicle housed in the cage body is heavy or is placed on one side, the chains a, a may be twisted due to sideways displacement or bending of the support metal c that supports the cage body. There is a risk that the chain will derail as a result of the roller e coming off the guide rail d, and the vehicle accommodated in the cage body b may be damaged due to the derailment. In order to prevent such accidents and protect the vehicle, there was a demand for a guide structure that would prevent rollers from coming off the track.In order to meet this demand, guide rails were provided on both sides of the chain and placed on both sides of the support metal fittings. There is also a device with a structure for guiding the rollers, but in this device, the cage body tends to interfere with the guide rail arranged inside, making the device structure complicated and expensive.

The present invention prevents derailment of the chain by reversing the direction of approximately half of the rollers attached to one side of the support fitting and having a flange on one side, thereby increasing the safety of the equipment and meeting the above requirements. The purpose is to provide a chain for multi-storey parking lots that can be adapted.

[Means for solving problems]

Hereinafter, one embodiment of the means of the present invention that can achieve the above-mentioned objects and meet the requirements will be described with reference to the drawings.

Chain 1 for multi-story parking lot in Figures 1 to 6
In this example, support metal fittings 4, 4 for supporting a cage body 3 for accommodating a vehicle are mounted facing each other on two chain bodies 2, 2 which revolve around the same and parallel circumferential line L. Moreover, the multi-story parking lot is provided with a guide rail 5 along the circuit line L, and the guide rail 5 can be rolled on a plurality of pin bodies 6 protruding from one side of the support fitting 4, and one side of the guide rail 5 can be rotated. A plurality of rollers 9 . A flange 7 is located on the other side 12 of the flange 7 and is rotatably attached to the flange 7. The pin body 6
is a pin that connects the inner link 15 and the outer link 16; , the inner link 1 with the pin body 6 inserted through the bushing 22.
A link plate 24 disposed on the outside of 5 is connected to the link plate 24. Also, the pin body 6 is connected to every second outer link 16.
Attach the support fitting 4 at the step.

In this example, the vehicle has wheels and runs on a road surface, and includes not only an automobile and a motorized motorcycle but also a manually propelled vehicle such as a bicycle and a handcart.

The chain body 2 also includes a pair of drive chain wheels 2 attached to the drive shaft 25S and the driven shaft 26S at equal intervals.
5 and a pair of driven chain wheels 26 in an endless manner, the two chain bodies 2, 2 can revolve around the same and parallel circumferential lines L, L. Note that instead of the chain wheel, a pair of annular rails formed in the same shape may be arranged facing each other and parallel to each other, and the chain body 2 may be made to revolve along the rails.

The guide rail 5 includes a pair of rail bodies 5A and 5B that are fixed to a frame that supports the drive and driven chain wheels 25 and 26 along the circumferential lines L and L, respectively. The rail bodies 5A, 5B are opposed to each other with a gap g between them, and have rolling surfaces 29, 29 on which the rollers 9 roll on opposing surfaces.

In this example, the guide rail 5 is provided only in the free span section between the driving chain wheel 25 and the driven chain wheel 26. Further, in this example, the support fittings 4 are provided on the two outer links 16 of the chain body 2 as described above.

The pin body 6 of the outer link 16 to which the support metal fitting 4 is attached is formed to be longer than those of other outer links 16, and the support metal fitting 4 is attached at the inner and outer ends of the pin body 6.
The links 31, 31 are fixed, and the outer end protrudes to a position beyond the guide rail 5, and the roller 9 is loosely fitted in this protrusion.

In this example, as shown in FIGS. 3 and 4, the support fitting 4 projects the pair of links 31, 31 toward the outside of the circuit line L, and supports the cage body 3 at the tip of the link 31. The bearing 32 is fixed.

In addition, the support fittings 4, 4 are two chain bodies 2, 2.
are aligned and provided in facing positions with respect to each other.

The cage body 3 has bearings 32, 3 for each support fitting 4, 4.
A frame body having a lower plate on which a vehicle can be placed is pivotally supported on a support shaft 33 that passes through both of the two.

Furthermore, by being attached to the support fitting 4, the cage body 3 can accommodate the vehicle at a predetermined position, and therefore can move the vehicle as the chain body 2 goes around and store the vehicle three-dimensionally.

As shown in FIG. 5, the roller 9 can pass through the gap g of the guide rail 5 and its rolling surfaces 29, 29
A flange 7 having an external dimension larger than the gap g is provided on one side of the rolling portion 36 capable of rolling.
Further, a plurality of bearings 39, 39, which are located approximately at the center of the roller 9 and whose inner diameters can fit into the guide rail 5, are fitted into the inner hole of the roller 9.

Also, the roller 9 has a flange 7 on one guide rail 5.
It is inserted with the distance piece interposed toward the support metal fitting 4 side, and is locked using a locking tool 41 such as a retaining ring attached to the tip of the pin body 6.

A roller 9 is fitted into the other pin body 6 with the flange 7 facing away from the support fitting 4, and is locked by a locking tool 41.

Therefore, a plurality of rollers 9, 9 which can roll the guide rail 5 on a plurality of pin bodies 6, 6 protruding from one side of the support metal fitting 4, and which are provided with a flange 7 on one side to prevent the wheels from coming off, are provided. In addition to being rotatably mounted, the flanges 7, 7 of the rollers 9, 9 are oriented oppositely to each other as described above, so that approximately half of the rollers 9
connects the flange 7 to one side 11 of the guide rail 5
Additionally, the remaining rollers 9 can be positioned with the flange 7 on the other side 12 of the guide rail 5.

[Effect]

By driving the driving chain wheel 25, the two chain bodies 2, 2 rotate on the respective circumferential lines L, L at the same speed and in the same direction. Further, as shown in FIG. 6, the roller 9 passes through the gap g of the guide rail 5 with the rolling portion 36 rolling, and one roller 9, that is, approximately half of the rollers 9,
A flange 7 is located on one side 11 of the chain body 2 to prevent the chain body 2 from moving outward. The other roller 9, that is, the remaining roller, has a flange 7 located on the other side surface 12 of the guide rail 5 to prevent the chain body 2 from moving inside. Therefore, unlike the conventional structure shown in FIG. 8, the support fitting 4 can be operated reliably and safely without coming off the guide rail 5.

〔Example〕

FIG. 7 shows another embodiment of the present invention. In this example, the link plate forming the outer link 16 and the link 31 of the support metal fitting 4 are formed as an integral side plate 51, and one side plate 51 has four pins, that is, a plurality of pins spaced at approximately equal intervals in the pitch direction. Body 6...
... are provided to protrude outward, and these pin bodies 6 ... are provided with a flange 7 on one side, and four or more rollers 9 ... are provided with the flange 7 facing inward and outward alternately. They fit loosely into each other. Therefore, approximately half of the rollers 9 have their flanges 7 positioned on one side of the guide rail 5, and the remaining rollers have their flanges 7 positioned on the other side of the guide rail 5. Note that the order in which the flanges 7 are oriented can be arbitrarily selected as long as approximately half of the flanges 7 are oriented in opposite directions. As described above, the multi-story parking lot chain of the present invention can be modified into various forms.

[Effect of idea]

As mentioned above, the multi-story parking lot chain of this invention is
The supporting metal fittings that support the cage body are attached facing each other to the two rotating chain bodies, and a plurality of rollers each having a flange are attached to a plurality of pin bodies provided on one side of the supporting metal fitting. is mounted on one side of the guide rail, and the rest are mounted on the other side of the guide rail so that they can rotate freely, so that the cage body will not be affected by the loading of heavy objects or unbalanced loads. Even if twisting or lateral displacement occurs, the rollers can reliably guide the support fittings without coming off the guide rails, preventing damage to the vehicle and increasing safety. In addition, the structure is simpler than the conventional one in which guide rails are provided on both sides, and the economic value can be increased.
